Requirements

• Existing installation running Chevereto V3.20

Test install (optional)

It is recommended to check first that a new Chevereto V4 installation can install and run in the target server. This is for detecting any conflicting requirement.

💡 Don't worry about license-domain restrictions. This is just a test install.

• Create a new website
• Install Chevereto V4
• Make sure it works without issues

If everything goes well you can delete this test installation and try it for real. If not, then go to Bug Tracking (opens new window) to share your findings.
